Energy-Efficient Channel Handoff for Sensor Network-Assisted Cognitive Radio Network
The visiting and less-privileged status of the secondary users (SUs) in a cognitive radio network obligates them to release the occupied channel instantly when it is reclaimed by the primary user. The SU has a choice to make: either wait for the channel to become free, thus conserving energy at the expense of delayed transmission and delivery, or find and switch to a vacant channel, thereby avo...
متن کاملEvolutionary Computing Assisted Wireless Sensor Network Mining for QoS-Centric and Energy-efficient Routing Protocol
The exponential rise in wireless communication demands and allied applications have revitalized academia-industries to develop more efficient routing protocols. Wireless Sensor Network (WSN) being battery operated network, it often undergoes node death-causing pre-ma...
متن کاملEnergy-Efficient Infrastructure Sensor Network for Ad Hoc Cognitive Radio Network
—We propose an energy-efficient network architecture that consists of ad hoc (mobile) cognitive radios (CRs) and infrastructure wireless sensor nodes. The sensor nodes within communications range of each CR are grouped into a cluster and the clusters of CRs are regularly updated according to the random mobility of the CRs. We reduce the energy consumption and the end-to-end delay of the sensor ...
متن کاملRefinement in Cognitive Radio Network for Spectrum Handoff
Cognitive radio (CR) can significantly improve spectrum efficiency by allowing the secondary users to temporarily access the primary user’s under-utilized licensed spectrum. Spectrum mobility issues arise when the primary user appears at the channels being occupied by the secondary users. The secondary users to return the occupied channel because the primary users have the preemptive priority t...
متن کاملAchieving a Better Energy-Efficient Cognitive Radio Network
Energy efficiency in cognitive radio networks has received lots of research attention lately due to the impact low energy efficiency has on the design, implementation and performance of the network. In this research, cognitive radio network as regards to energy efficiency has been analyzed. The importance of energy efficiency in cognitive radio networks and sources of unnecessary energy consump...
